D)100:1

Question

Quizplus · Accepted Answer

The difference in magnitude between two stars is related to their brightness ratio by the following formula:

brightness ratio = 2.512^(magnitude difference)

Using this formula, we can calculate the brightness ratio for a magnitude difference of 5:

brightness ratio = 2.512^5 = 100.34

Therefore, the correct answer is D) 100:1.
